Marimba joins the Microsoft management alliance Program

Marimba, Inc., a leading provider of systems management solutions built for
e-business, today announced it has joined the Microsoft Management Alliance
(MMA), a vehicle for software developers to obtain assistance in developing
excellent products and achieve market success on Microsoft platforms.

"Marimba values this opportunity to join the MMA program, because it allows
us access to Microsoft's product directions so that we can best 'embrace and
extend' their advanced technology," said Kia Behnia, vice president of
product marketing for Marimba. "Additionally, being a part of MMA provides
us with technical and marketing resources, product guidance, industry
knowledge, and further strengthens one of our most critical relationships."

"Companies like Marimba can use the Microsoft Management Alliance to learn
how to utilise the extensive management technologies that Microsoft has
built into Windows operating systems and products," said David Hamilton,
director of product management, Management Technologies, Microsoft
Corporation. "By taking advantage of these management services, our partners
will be able to create even more successful products that meet customer
needs in reducing costs and improving system reliability."

The Microsoft Management Alliance partner program, launched in October 2000,
is a new tool to help hardware and software companies utilise Microsoft's
various management technologies and products. Microsoft .NET Management
Services is a collection of management technologies and standards within the
Windows operating system that developers can incorporate into their
management software as well as the different types of networked applications
that are being managed. In addition, the inaugural Microsoft Management
Alliance partner program will provide technical information and marketing
resources for developers and independent software vendors that build
applications on top of the .NET Management Services.
